2GB DDR2 SO-DIMM for iMac Core 2 Duo

This 200-pin DDR2 667 MHz module upgrades an Apple iMac "Core 2 Duo" 2.0 17-Inch from late 2006. It delivers 2GB of unbuffered, non-ECC memory rated at PC2-5300 with CL5 timings. The stick uses major-brand chips and operates at the standard 1.8V for this platform.

Verify your iMac model and slot count

Confirm the computer is the 17-inch iMac identified as MA590LL, iMac5,1 or A1208 before ordering. That system accepts a maximum of 4GB across two sockets, with no more than 2GB per socket. This single module fills one slot; add a second identical stick only if the other socket is empty.

Plain green PCB fits the factory slot

The module has no heat spreader, so its low profile matches the original Apple memory form factor. Gold-edge contacts on the 200-pin SO-DIMM connector seat directly into the iMac's user-accessible memory door. A limited lifetime warranty from the manufacturer covers defects when purchased through authorised channels.

Questions about this item

Does the box contain only the 2GB DDR2 667 SO-DIMM or do I need to buy anything else?

The package includes one 2GB DDR2 667 200-pin SO-DIMM stick. No extra parts are required for installation.

My iMac has two slots and a 4GB maximum — should I choose one 2GB module or two?

Each slot accepts up to 2GB. Add a second identical module to reach the 4GB limit, or install a single stick for a 2GB upgrade.

The spec says PC2-5300 667 MHz — what speed will the memory actually run at in my iMac?

The module is rated at 667 MHz CL5. The iMac's memory controller will operate it at that speed and timing.
